Now I have these outputformats

OUTPUTFORMAT
  NAME "SHAPEZIP"
  DRIVER "OGR/ESRI Shapefile"
  MIMETYPE "application/shapefile"
  FORMATOPTION "STORAGE=memory"
  FORMATOPTION "FORM=zip"
  FORMATOPTION "FILENAME=shape.zip"
END
OUTPUTFORMAT
  NAME "CSV"
  DRIVER "OGR/CSV"
  MIMETYPE "text/csv"
  FORMATOPTION "LCO:GEOMETRY=AS_WKT"
  FORMATOPTION "STORAGE=filesystem"
  FORMATOPTION "FORM=simple"
  FORMATOPTION "FILENAME=out.csv"
END

You can try them:

http://188.64.1.61/cgi-bin/mapserver_wfs?service=wfs&version=1.1.0&request=getfeature&typename=municipalities&outputformat=CSV
Result is probably "Failed to open result file" 

http://188.64.1.61/cgi-bin/mapserver_wfs?service=wfs&version=1.1.0&request=getfeature&typename=municipalities&outputformat=SHAPEZIP
Result is probably an empty zip file.
